+Routine Description:
+  This service is called from Index == 0 until it returns EFI_UNSUPPORTED.
+  It allows discontiguous memory regions to be supported by the emulator.
+  It uses gSystemMemory[] and gSystemMemoryCount that were created by
+  parsing the Windows environment variable EFI_MEMORY_SIZE.
+  The size comes from the varaible and the address comes from the call to
+  WinNtOpenFile. 
+
+Arguments:
+  Index      - Which memory region to use
+  MemoryBase - Return Base address of memory region
+  MemorySize - Return size in bytes of the memory region
+
+Returns:
+  EFI_SUCCESS - If memory region was mapped
+  EFI_UNSUPPORTED - If Index is not supported
